Both species exist, one in New Zealand(Cyathia) the other In Australia/Tasmania. Loves shade, and min. temp minus4 celsius. Could do well in your climate out of doors.
Not at all bad, just difficult to keep humidity levels high enough for the plants. The more light the better growing conditions, there are so many variables here. Ferns such as a Tree Fern, need lots of daylight in a Maritime climate... less in a desert... but more humidity... and soil conditions are equally important, moist but not wet.
Looking healthy too! I was concerned with the fronds' curling, thinking the humidity was a tad low for the Fern?
I think those curled fronds are just new growth that haven't expanded fully yet. My rabbit's foot fern does this.
LOL! Oh dear, I should have been more precise, I was referring to the mature fronds, that had a peculiar under curl that I was associating with low humidity....lol! My green thumbs went numb to the keyboard... The emerging fiddle head shaped frond was not my meaning for the curled up frond :) Sorry for the confusion everyone...
